# Interpolation-based image scaling

The MPV player user shader for interpolation-based image scaling. Designed for experimental, testing or educational use.

## Usage

- If you place this shader in the same folder as your `mpv.conf`, you can use it with `glsl-shaders-append="~~/interpolation_based_image_scaling.glsl"`.

- The shader is controlled under `user configurable` section by changing macro values and by directly implementing filter kernel.

- Requires `vo=gpu-next`.

## Notes

- The shader is not optimised for speed.

- Antiringing behaves a bit differently compared with the same technique implemented in separated passes.

- In general, you may expect slightly different results from different implementations of resampling algorithms.

- For `linearize` and `delinearize` macros see `pl_shader_linearize` and `pl_shader_delinearize` functions in https://github.com/haasn/libplacebo/blob/master/src/shaders/colorspace.c

- In general for sintax of mpv user shaders see https://libplacebo.org/custom-shaders/
